Selects
The select is READ-ONLY "function", that helps to get direct access to some parts of SIP message within the script (like @to, @cseg.method, @msg.["P-anyheader-youwant"]), but generally could be seen as function returning a string with certainnumber of parameters.
Each module can extend the syntax the select framework understands registering it's own select table. Look on TLS module or db_ops as good samples.
